16 Prof. J. Reiuhardt on the Birds 



92. ^Fratercula cirrata (Pallas). 



I insert this bird upon the authority of Pastor Moschler, who 

 mentions that he had received a specimen "from Greenland" 

 in 1846 (Journ. f. Ornith. 1856, p. 335). 



93. Uria brue.vnichii, Sab. 



9J^. Uria troile, Linn. 



The Uria ringvia, Briinn. [U. troile leucophthalmos, Fab.) is 

 only a variety of the common U. troile, and very rare in Green- 

 land. 



95. Uria grylle^ Linn. 



96. Arctica alle (Linn.). 



97. PuFFiNus major, Fab. 



98. ^Puffinus anglorum, Ray. 



99. Thalassidroma leachii (Temm.). 



100. Procellaria glacialis, Linn. 



In a former list (Vidensk. Meddel. 1853, p. 69 seq.) I ad- 

 mitted as a second species the P. minor of Mr. KJEerbolling. 

 A stricter examination has, however, convinced me that it has 

 been established without sufficient reason. The pretended dif- 

 ference in colour at least is not constant, if ever existing ; and 

 the small Fulmars are not at all (as it has been stated) confined 

 to North Greenland. The smallest I ever saw (smaller than 

 that of which the measurements are given by Mr. Kjserbolling) 

 was sent to the Royal Museum from South Greenland. On the 

 other hand, I have received examples from North Greenland 

 corresponding exactly in size with others from the Far Islands. 



101. Stercorarius catarrhactes (Linn.). 



102. Stercorarius pomarinus (Temm.). 



103. Stercorarius parasiticus (Linn.). 



104. Stercorarius buffonii (Boie). 



105. Larus marinus, Linn. 



106. Larus glaucus, Linn. 



I have not succeeded in distinguishing a Larus arcticus or 

 L. glacialis from the true L. glaucus. It is quite true that some
